Banks and thickets, especially along rivers and borders of forests.
Vigorous plants from fencerows in Monroe Co. with leaves intermediate between this species and C. foemina are apparently hybrids; they have high pollen viability and fruit set. A collection (J. S. Wilson 261, MICH) from along a ditch in the same county was considered to be a hybrid with C. amomum subsp. obliqua; it has longer and narrower leaf blades than in either parent and has almost no viable pollen.
Superficially resembling a broad leaved Cornus foemina, this species regularly achieves a larger size and can occasionally become a small tree.
